CHURN.

Specification of Letters Patent.

Patented Dec. 31, 1912.

'agitating the milk and cream in the body or barrel are so arranged anddriven as to turn in opposite directions, this motion being imparted bysuitable gearing mechanism mounted above the churn body or barrel andconnected to the dashers, respectively.

The primary object of our present invention is to provide improvedoperating mechanism for imparting the desired motion to the rotatabledashers, whereby they may be operated at a high rate of speed, or at areduced rate, according to the condition of thematerial within thechurn-body, the construction and arrangement of the mechanism, andbearings for the shafts, being such that the operation of churning maybe effected very quickly and with the expenditure of a minimum amount ofmanual power.

The construction and operation of our improved churn is hereinafterfully set forth, and what we claim as new is specifically set forth inthe appended claims.

In the accompanying drawings which form a part of this specification z.Figure 1 is a side view, partly in section, showing a complete churnconstructed in accordance with our invention. Fig. 2 is a front view ofthe upper part of the churn, including the operating mechanism. Fig. 3is an enlarged detail sectional, View, showing the main driving-shaftand parts carried thereby.

Like numerals of reference indicate like parts in all the fi ures of thedrawings.

In the present instance the bod 5 of the churn is cylindrical and provied at its upper end with a removable top 6, the latter supporting.l theo erating mechanism and dashers, erein these parts may be all removedfrom the body of the churn to permit of free access thereto. At thecenter of the bottom of the churn-body there` is a boss 7, having arecess or depression to form a seat for one of the a ter described;whereby` dashers and roperly center both dashers 1n said churnody, aswill be apparent.

The upright frame for supporting the operating mechanism consists `of amain rectangular portion 8 and an upward extension 9 at the forward endthereof, the front plate or upright 8 forming the front of both the mamportion and extension. This supporting-frame is rovided with a b'aseplate 8b, which rests dlrectly upon the cover or top 6 of the churn andis fastened thereto by rivets 10, or other suitable fastening means.

- Projecting inwardly from the rear upright of the supporting-frame, atasuitable distance above the base-plate, is a bearingarm 11, having acentral openin 11 at its end to receive one end of the main drivingshaft12, the other end of said shaft being supported in a slidable sleeve 13,hereinafter particuarly referred to. The bearingarm 11 is provided witha suitable ballbearing for the shaft 12, consisting in the presentinstance of a bearing-ring 14, retaining-cap 15, and interposedanti-friction balls 16, the cap being threaded on the outer end of theIarm as shown in Fig. 3, and the shaft provided with a collar 12 toprevent longitudinal movement. y

Keyed upon the driving-shaft 12, adjoining the end of the bearing-arm11, is a large bevel gearwlieel 17, in mesh with bevel pinions 18 and19, at the upper and lower end, respectively, of vthe supporting-frame8, the bevel-pinion 19 Vresting directly upon the base-plate 8b andconnected tothe tubular extension 2O"L of a rectangular dasher-frame 20,ounted for rotation in the ch'urn body.

The evel-pinion 18 is connected to a rod 21, which passes downwardlythrough the tubular extension 20 and through the rectan'gularflasher-frame 20, and bears at its lower end in the seat 7 on the bottomofthe churn-body, whereb as will be noted,fthe dasher-frame 20 an rod 21will be rotated in opposite directions by the driving gearwheel `17, byreason of the location of the pinions at op ositesides of the center ofsaid gearwhee In the present 'instance the rectangular dasher-frame 20is provided with blades 20b which extend from the Sides thereof at anupward angle toward the center of the frame', and the rod 21 is providedwith similar blades 21, which extend.. at a downward angle therefrom andlos rotate on a plane intermediate the blades 119 20h, so that as thedashers are revolved in opposite directions they will thoroughly agitatathe milk and cream to quickly form butter.

The bearing-sleeve 13, which is slidable' upon and rotates with thedriving-shaft '12, passes through the front upright 8a of thesupporting-frame and has a ball-bearing therein, the anti-friction balls29 being retained in place by a flanged collar The sleeve has a collar13a, and a squared portion beyond, to which latter the crank-handle 2lmay be applied. Keyed on the inner end of this sleeve is a pinion 25,which may be moved in and out of .mesh with a large supplementalilrivinggearwheel 26, the latter being mounted in the upper extensionot' the supporting-frame on a shaft 27 jrmrnaled insuitableball-bearings 2S and 29. ln order to hold the pinion 25 either in or outof mesh with the driving gearwheel QG We provide a latch-plate 30pivoted on the upright 8 and adapted to engage at either side of thecollar 13a, the upright 8a being provided with a ,recess Sc to receivethe collar when the sleeve is moved inward to dispose the pinion out ofmosh with the driving gearwheel 26. 1

in the operation of the churn the mille and cream are agitated first byturning the shaft lsmthatrthelarge bevel gearwheel 17 will be driventhrough theYV intervention ,of the large driving-gearwheel 26 and pinion25, the parts being arranged as shown in Fig. l p with the pinion 25`inmesh with said large driving-gearwheel 26 and the crank-handle. inengagement with the shaft 27. By this arrangement, as will be seen, thedashers will be rotated rapidly by a comparatively slow motion of thecrank-handle. Now when the butter begins =to form, requiring additionalpower to turn the dash'ers the pinion 25 is slid out of mesh with thedriving-gearwheel 26 and the crank-handle applied to the shaft 18-l2thereby applying 'the power directly tothe bevel-gearwheel 17. lit willalso be noted that the particular construction of the dashers serve toeffect a thorough agitation of the milk and cream by reason of the factthat the blades are disposed at an inclinationgaateinepart-erstirringinotiorV Iadtliellades on one dasher pass thoseon the other in an opposite direction.

Lofiaeee Having thus described our invention, we

claim:

l. In a churn, the combination with rotatable dashers, of pinionsconnected to said dashers, a gearwheel inv mesh with the pinions torotate the dashers in opposite directions, a main shaft to which saidgear- Wheel is fixed, a. sleeveslidable on the shaft and having asquared outer end, a pinion fixed on the sleeve, a large gearwheelmounted above said Pinion so as to mesh therewith, ay shaft 'for thelast mentioned gearwheel, and a crank-handle, substantially as shown anddescribed.

2. In a churn, the combination with the body or' barrel, of asupportingframe mounted thereon and having a bearing-arm projectinginwardly from one side thereof, ball-bearings in the end of the arm, amain driving-shaftk mounted at one end in'said4 ball bearings, a sleeveslidable on said shaft and mounted in ball-bearings in the frame, abevel gearwheel on the shaft, a pinion on the sleeve, and a largedriving gearwheel with which the pinion is adapted to mesh; togetherwith pinions in mesh with the bevel gearwheel at opposite sides of thecenter thereof, and rotatable ydashers connected to said pinions,respectively, substantially as shown and for the purpose set forth.

3. ln a churnthe combination with rotatable dashers, of pinionsconnected to said dashers, a large gearwheel lin esh with said pinions,a shaft for said gearwheel, a sleeve.

mounted in bearings and slidably connected to the shaft, a collar onsaid sleeve, and a latcli.plate adapted to engage at either side of thecollar; together with a pinion on the sleeve, a driving gearwheel withwhich said pinion is adapted to mesh, a shaft for the la'st mentionedgearwheel, and a crankhandle for turning the shafts, substantially asshown anddescribed.

lin testimony whereof we have signed our names to this specification inthe presence of two subscribing witnesses.
